How were Nixon's successes overshadowed by scandal?

Nixon's presidency had notable achievements, such as the opening of diplomatic relations with China and the establishment of the Environmental Protection Agency. However, these successes were largely overshadowed by the Watergate scandal, which involved a break-in at the Democratic National Committee headquarters and subsequent efforts to cover it up. The scandal eroded public trust in the government and culminated in Nixon's resignation in 1974, overshadowing his policy accomplishments and defining his legacy. As a result, his significant foreign and domestic policies are often eclipsed by the controversies surrounding his administration.
